用LMI技术和H∞控制对液压缸的位置系统进行了控制,控制效果由仿真曲线可以看出:H∞控制的优点是针对参数不确定性的系统,即使系统参数发生变化也能使系统达到强稳定,由此可以验证此控制器有很大的工程应用价值。
The position system of the hydraulic cylinder is controlled with LMI technology and H∞ control, the control effect can be seen by the simulation curve that the advantages of H∞ control is based on the uncertainty parameters system, even if the system parameters change, the system also can achieve strong stability, which can verify that the controller has a great application value in engineering.
